Zusammenfassung: | A method for singulating an assemblage into a plurality of semiconductor chips is specified, wherein an assemblage comprising a carrier, a semiconductor layer sequence and a metallic layer is provided. Separating trenches are formed in the carrier. The assemblage is subjected to mechanical loading, with the result that the metallic layer breaks along the separating trenches and the assemblage is singulated into semiconductor chips, wherein the singulated semiconductor chips each have part of the semiconductor layer sequence, of the carrier and of the metallic layer. A semiconductor chip is furthermore specified. |
